As available intelligence data and information expand in both quantity and variety, new techniques must be deployed for search and analytics. One technique involves the semantic enhancement of data through the creation of what are called ‘ontologies’ or ‘controlled vocabularies.’ When multiple different bodies of heterogeneous data are tagged by means of terms from common ontologies, then these...

Szemerédi’s Regularity Lemma is a fundamental tool in graph theory: it has many applications to extremal graph theory, graph property testing, combinatorial number theory, etc. The goal of this paper is to point out that Szemerédi’s Lemma can be thought of as a result in analysis. We show three different analytic interpretations.

Remote sensing images obtained by remote sensing are a key source of data for studying large-scale geographic areas. From 2013 onwards, a new generation of land remote sensing satellites from USA, China, Brazil, India and Europe will produce in one year as much data as 5 years of the Landsat-7 satellite. Thus, the research community needs new ways to analyze large data sets of remote sensing im...

In this paper, we investigate whether an increase in analyst monitoring, which improves the informational efficiency of stock prices, necessarily translates into firms’ managers taking more value-enhancing decisions (“real efficiency”). We show that when the manager’s compensation is tied to stock prices, then an increase in analyst monitoring weakens managerial incentives by making the firm’s ...

Forensic science has been slow to develop as a recognised field of study. Over the past 30 years, analytical and forensic science have developed together; though the application of new analytical techniques in forensic work is retarded by the necessity of having methods of proven reliability. The many techniques now applied in forensic analysis—microscopy, spectroscopy of all types, x-ray analy...

Many engineers come into the performance world from different backgrounds and lack the appropriate education. For example, a software developer may be challenged to look at the performance problems in some code and might transition into software testing as a result. He learns what he needs to know on-the-fly. Many times, he does not know that he needs to know something and does what he can. If ...

Do analysts serve as external monitors to managers, or do they put excessive pressure on managers? This study examines the role analysts play in corporate governance by focusing on the effect that their scrutiny has on earnings management. Controlling for other firm characteristics, including institutional ownership, I find that firms followed by more analysts manage their earnings less. To add...
